Spi Z9302 Micrometer Anvil 1 to 12 Inch

Product Description

The SPI Z9302 is a comparator-type micrometer anvil designed as a replacement or spare accessory for outside micrometers with a measuring range of 1 to 12 inches. Anvils are the stationary contact point against which a workpiece is held during measurement. A worn, damaged, or incorrect anvil directly affects measurement accuracy, making proper replacement critical in any precision-measurement environment. This part is installed by machinists, metrologists, toolroom technicians, and calibration specialists who maintain measurement instruments to tight tolerances. At 0.15 pounds, the Z9302 is a compact, single-piece component suited for bench and field micrometer service.

The Z9302 comparator anvil is intended for use with outside micrometers spanning the 1 to 12 inch range. Comparator-type anvils are typically used in applications where a flat, stable reference surface is required for repeatable contact measurement. This accessory is appropriate for both shop-floor measurement tools and laboratory-grade instruments that require periodic contact-surface replacement due to wear or damage from regular use.

Key Features

• Comparator-type anvil geometry for flat, stable workpiece contact
• Compatible with outside micrometers from 1 to 12 inches in range
• Lightweight single-piece construction at 0.15 pounds
• Direct replacement accessory for worn or damaged micrometer anvils
• Packaged as a single-unit replacement component

Compatibility

Designed for use with outside micrometers having a measuring range of 1 to 12 inches that accept a comparator-style replacement anvil.

Installation Notes

Anvil replacement should be performed by a qualified metrologist or toolroom technician familiar with micrometer disassembly. Before servicing, ensure the micrometer is removed from service and cleaned of any coolant, chips, or debris. Follow the instrument manufacturer's service documentation for proper anvil seating and spindle alignment procedures. After installation, verify calibration against a certified gauge block before returning the instrument to service.
